It must be this thing in screen-common.less
.background-image-svg( 'images/headbg-gradient.svg', '' );
that produces
background-image: url('');
which then fails.

The code should just use .background-image. Introduced in Ie6f5b6b87b475953274688fc4640f9fa17184fa4.

I am not sure how CSSMin should handle this, I leave that to someone else.

In https://gerrit.wikimedia.org/r/#/c/423712/ I've been trying to make a test case that asserts an exception but I can't seem to reproduce the bug.

I still can't trigger the error even with .background-image-svg( 'images/headbg-gradient.svg', '' ); but perhaps I'm just not doing it right.

• mmodell added a comment.Apr 4 2018, 7:10 PM

Ok now I've got a good test case.

This is the #1 and #2 logspammer right now and we're only on group 1:

@Krinkle I'd like to merge https://gerrit.wikimedia.org/r/#/c/423712/ and/or https://gerrit.wikimedia.org/r/#/c/424041/ to resolve the logspam which is now affecting 1.31.0-wmf.28. Would you mind giving it a code review?

@mmodell Your MonoBook patch https://gerrit.wikimedia.org/r/424035/https://gerrit.wikimedia.org/r/424041 looks good to me, I'm merging it on master and I support backporting it.
